Overview
The AD7660ASTZ is a 16-bit, 100 kSPS (kilosamples per second) CMOS successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single 5 V power supply and features an internal conversion clock, error correction circuits, and both serial and parallel system interface ports. The AD7660 is hardware factory-calibrated and comprehensively tested to ensure high performance in terms of signal-to-noise ratio (SNR), total harmonic distortion (THD), gain, offset, and linearity. It is fabricated using Analog Devices’ high-performance 0.6 micron CMOS process and is available in a 48-lead LQFP (7mm x 7mm) package, with an operating temperature range of –40°C to +85°C.
